invention relates to improvements. demountable truck bodies. and more parti larly 9- vel dem ruck bcdi s aving r tractable standards and is related to patent application bearing the Serial #:lfiilfl54, filed May 8, 1950, for Improvements in Methods of Load handling, in that it involves one form of demountable truck body employed therein.

In trucking practice, it has been found that one mobile unit may advantageously be employed in connection with several truck bodies provided with retractable standards so that a mobile unit may be backed under the body while it rests on its standards after which the standards may be retracted and the body secured to the mobile unit and transported with its load. After such body has been dumped of its contents it may be returned to a loading site, the standards may be extended, and the mobile unit may be driven clear of the body which can be left at said site for convenient loading thereof and the mobile unit may be driven away to handle similar demountable bodies.

An object of the invention is to provide a demountable body with retractable standards having special features of construction which permit easy backing thereunder of a mobile unit.

Another object of the invention is to provide a device of the type which will effect economies in trucking operations by reason of the fact that a. plurality of the bodies may be used in connection with a single mobile unit.

Other and further objects of the invention will appear as the description proceeds, reference being had to the accompanying drawing, in which:

Fig. 1 is a view in perspective from above of a demountable truck body shown in position for loading with the retractable standards thereof in extended position supporting said body.

Fig. 2 is a side view of said body in position on a mobile unit with the standards thereof in retracted position.

Fig. 3 is a vertical sectional view through one of the front end standards of the device.

Fig. 4 is a view on line 4-4 of Fig. 2.

Referring more particularly to the drawing, the numeral I represents the device generally having a bottom I I, side walls I2 and I3, and end walls I4 and I5. The body It is provided with the transverse and vertical ribs I6 and I! disposed exteriorly 0f the bottom I I and sidewalls I2 and I3. A pair of trunk members I8 and I 9 are formed at the rear corners of the body I0. Each trunk I8 and I9 has a top wall and contains a downwardly projecting sleeve 2| open at s lower end to receive. the, telescopic. standard W 22 which is nrerided with a surface conng teat 2.3 pivoted at. 24 of said standard. foot. 23 has a. hand strap 25 for. manually retracting the tel scopic standard 22. Each side wall I2 and I3 is provided adjacent the front end I4 with a bracket member 26 having a downwardly disposed tubular spindle 21 which has a lower retaining collar 28. The spindle 21 and the collar 28 are apertured to accommodate the retaining bolt 29. The bolt 29 is secured by the nut 30 exteriorly of said collar 28. A sleeve 3| is held for free rotation on the spindle 21 by means of the collar 28 and the bolt 29. The sleeve 3| and the spindle 21 are apertured as at 32 to accommodate a pin 33 retained on a flexible chain 34. The pin 33 is used to fix the sleeve 3| against rotation on the spindle 27. A tubular arm 35 is fixed to the sleeve 3| and to the standard receiving sleeve 36 on the outer end of said arm 35. The standard 3'! is shown in Fig. 3 in raised position within the sleeve 36 and retained in this position by the pin 38 which is inserted through an aperture at 39 of the sleeve 36 and a registering aperture as at 40 of the standard 31. In Fig. 4 it will be seen that the sleeve 2| is welded at points 42 and 43 interiorly of the rear outer corner 44 of the truncated element I9 and that a brace plate 45 is welded at 46 to said sleeve 2| and at 41 to the outer wall of the trunk element I9.

A pair of guide rails 48 and 49 flared outwardly at their frontal ends 50 and 5| are subjoined to the bottom II of the body I0.

As shown in Fig. 1 the standards 22 and 3! are extended and are held in position by pin 25 inserted through apertures in the sleeve 2| and the standard 22. The arm 35 has been swung outwardly of the body ID and has been fixed by means of the pin 33. A mobile unit 52 may be backed under the body I0 and the wheels thereof 53 will thus clear the standards 3'! in their laterally extended positions. The guides 48 and 49 will receive the lift frame 55 of the mobile unit. After the lift frame 55 on the mobile unit 52 has been raised a short distance, the standards 31 and 22 can be raised manually and secured in the lifted position by means of the pins 38 inserted through the apertures as at 40. The body IIl may then be .lowered to a carrying position on the mobile unit 52. This process is reversed when the body I 0 is placed for the reception of a load.

It will be understood that the device is capable of many modifications in structure and design,

without departing from the spirit of the invention, within the scope of the appended claims.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent of the United States, is:

1. In a box truck body, an exterior laterally projecting bracket, a tubular element extending vertically downwardly therefrom, a cylindrical bearing adjacent the lower end of said tubular portion, a sleeve element embracing said bearing, an arm rigidly connecting said sleeve with an inverted tubular socket, a tubular standard movable freely within said socket, the said socket and standard each having horizontally aligned apertures, and pin means for relatively fixing the standard in selected positions in said socket.

2. In combination with a boxtruck body, an exterior laterally projecting wali'bracket thereon, a tubular element extending vertically downwardly cfrom said bracket, an integral cylindrical bearing adjacent the lower end of said 'tubular portion, a sleeve element embracing said bearing, shoulder means on said tubular portion for restraining vertical movement of said sleeve, aninverted tubular socket, an arm rigidly con- '4 necting said sleeve with said socket, a tubular standard movable freely within said socket, the said socket and standard each having a plurality of horizontally aligned apertures, pin means for relatively fixing said socket and standard, and a foot element at the base of the standard comprising a base plate, a plurality of spaced vertical plates fixed on the upper surface thereof, and an axle journalled in said vertical plates and horizontally through thelower end of said tubular standard.
